I followed wiccaan's tutorial and I have made everything, but at the time to compile i get this error:

ID3D9Wrapper_Device.obj : error LNK2001: unresolved external symbol "public: virtual unsigned int __stdcall Direct3DDevice9Wrapper::GetAvailableTextureMem(void)" (?GetAvailableTextureMem@Direct3DDevice9Wrapper@@UAGIXZ)
1>C:\Users\ivan\Desktop\DX_Hook\Debug\DX_Hook.dll : fatal error LNK1120: 1 unresolved externals

I know it's the linker but i have no idea on how to fix it. Help would be greatly appreciated.

I couldn't reply on the thread because it said i needed some kind of special permission. And also it wouldn't let me send you a pm.

Are you linking against d3d9.lib?

I did include all the lib files i was supposed to include. I even linked the detours too after following the instruction of the detours just to be sure.

C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Lib\x86

Maybe it's cuz i have the newest DX SDK? but it does have the d3d9.lib

Make sure you have recreated the function GetAvailableTextureMem in your wrapped device as well. You have to 'proxy' all the functions or you will get errors.

OMG, thx man. That was stupid of me. I totally didn't see that i didn't recreate that function. Thank you very much I was just missing that Very Happy

.

Although i get this warnings:

BTW, is there any other forum with the results like:

Results of using this tutorial can be such as:
extalia[.]com/forums/viewtopic.php?f=45&t=2597

or better yet, if you could help me with making the models wire-framed.

I did find another tutorial that says:

To run the game in wireframe add:
m_pD3Ddev->SetRenderState(D3DRS_ZENABLE, D3DZB_FALSE);
m_pD3Ddev->DrawIndexedPrimitive(Type,BaseVertexIndex, MinVertexIndex, NumVertices, startIndex, primCount);
m_pD3Ddev->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE);

where would i add it or what will i have to change in order for that to work on wiccaan's tutorial wrapper.

The Extalia link is dead because the site is gone. I wrote the tutorial, the copy of it in the Programing+ section is the same as what it was posted on Extalia. I never wrote the 2nd part since I didn't have the time to when I first wrote the tutorial.

If you want the whole game to go into wireframe just set D3DRS_FILLMODE to D3DFILL_WIREFRAME with SetRenderState.

If you are trying to do it per-specific texture or object you will have to filter them out one way or another. Most cases you will monitor and alter them inside of DrawIndexedPrimitive.

Should i just ignore the warnings?

I saw in a microsoft forum that it doesn't affect anything except debugging.

And about the wireframe thing:

There's no D3DRS_FILLMODE in the project so should i put it in the ID3D9Wrapper_Device.cpp

like this:

HRESULT Direct3DDevice9Wrapper::SetRenderState(D3DRENDERSTATETYPE State,DWORD Value)
{
Direct3DDevice9->SetRenderState(D3DRS_FILLMODE);
return Direct3DDevice9->SetRenderState(State, Value);
}

I'm sorry i'm just learning and i got no idea Sad

The Detours warnings, yea you can ignore them. D3DRS_FILLMODE is a render state, which is part of the Direct3D runtime, it's not part of the hook.

Inside of SetRenderState you can check if the incoming state is for D3DRS_FILLMODE and force it to a different value, or you can monitor for a hotkey in a thread elsewhere and toggle it etc.

The code you gave me had errors when i tried to compile so i changed it to this:

The errors are because my objects were named differently. It's fine, you just had to change them to match your object names and class names etc.

The engine might not call SetRenderState specifically with D3DRS_FILLMODE so you may need to do it manually yourself from another spot in your hook.

Cant i just remove the if so that it will always set the value to wireframe?

Just removing the if line

You'd want to let the original call go through first before you alter the params any. You can also just call SetRenderState twice like this:
